 - `SITES` is list of sites separated by `:` colon to migrate. e.g. `SITES=site1.domain.com` or `SITES=site1.domain.com:site2.domain.com` By default all sites in bench will be backed up.
 - `WITH_FILES` if set to 1, it will backup user-uploaded files.
+- By default `backup` takes mariadb dump and gzips it. Example file, `20200325_221230-test_localhost-database.sql.gz`
+- If `WITH_FILES` is set then it will also backup public and private files of each site as uncompressed tarball. Example files, `20200325_221230-test_localhost-files.tar` and `20200325_221230-test_localhost-private-files.tar`
+- All the files generated by backup are placed at volume location `sites/{site-name}/private/backups/*`
